WALTER S. ADAMS, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOB TO THE J. G.BRILL COMPANY, OF PHILADELPHIA, PENNSYLVANIA,- A CORPORATION OF PENNSYL-VAN IA.

CAR-TRUCK.

Specification of Letters Patent.

Patented Aug. 15, 1911.

To all whom it may concern:

Be it known that I, WALTERS. ADAMS, a citizen of the United States, anda'resident of the city and county of Philadelphia and Stateof'Pennsylvania, have invented a new and useful Improvement inCar-Trucks, of .1 t

j usual wheels 2,'axles 3, axle boxes 4, pedestal 5, axle box springs 6,top chord 7, tie bars 8, together with the other usual parts which arewhich the'following is aspecification.

The object of my invention is to provide a car truck'whichwi'll besmooth and easyriding when operated at high speed such as sixty orseventy miles an hour. This object is accomplished by my invention, oneembodiment of which is hereinafter set forth.

For a more particular description of my invention, referenceis to behad'tothe accompanying drawings, forming a part hereof, in which:

Figure 1 is a side elevation. of a truck providedwith my improvements.For convenience of-illustration' in this and the two following figures,the old and well known parts of the truck are shown in dotted lines.Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1, lookingin'the direction of the arrows.

. on the line 33 of Fig. 2, looking in the direction of the arrows. Fig.4 is a perspective view of a band for an elliptic spring. Fig. 5 is aperspective view of a spring plank and portions of elliptic springsmounted thereon. Fig. 6 is a perspective view of a plate which isadapted .to be placed between a spring plank bands of a pair of ellipticsprings. Fig. 7 is a planview of the structures shown in Fig. 5. Fig. 8shows a T-bolt. Figs. 9 and 10 arecross sections showing the springplank and elliptic-springs-together with the con.- necting parts. Fig.11 is a sectional view taken on the line 11-11 of Fig. 7 ,looking in thedirection of the arrows. Fig. 12 is a plan view of a spring cap. Fig. 13is a sectional view taken on the line 1313 of Fig. 12, looking in thedirection of the arrows. Fig. 14 is a side elevation of this cap. Fig.

15 is a longitudinal section thereof. Fig. 16

is a side elevation of one of the supports or saddles of the sand plank.Fig. 17 is a longitudinal section of the same, taken on the line 1 717'of Fig. 16. Fig. 18 is a side elevation of a portion of an equalizingbar. Fig. 1-9 is'a plan view of the same. Figs. 20, 21 and 22 aresectional views on the lines 2020,'-21-21 and 22--22, respectively, of

Fig. 3 is a sectional view taken and the Fig. 18, looking in thedirection of the arrows.

Throughout the drawing similar reference characters designate similarparts.

My improved truck 1 is provided with the characteristic of 'the type oftruck shown.

Each top chord 7 has near each pedestal 5, a i l1nk'9 which is bent soas to engage three sides of the top chord 7 and hang with substantialrigidity therefrom. Near the lower edge of the said top chord 7 eachlink is bent outwardly and downwardly and a little lower it is bent soas to stand vertically and finally its lower ends are turned slightlyupwardly and inwardly in the conventional various views of the" mannerto engage a spring seat 10,- which is a supported as shown on the lowerends of each link 9; The seat 10 may be' given any suitable shape but ispreferably made as shown.

A suitable coil spring 11 is carried by the seat 10, and is surmountedby a cap 12' that has guiding lugs 13 which are'adapted to rub againstthe vertical parts of the-link 9, in which it is placed and thiscap 12also has a journal bar 14 adapted to receive the. rounded ends of' anequalizing bar 15: -The equalizing bar 15' is not straight, but is'bentin a manner similar to the-equalizing bar of any ordinary 'Master CarBuilders -truck and is preferably made as shown, that is with a curvedupwardsurface at, its-cen er as shown in Fig. 20, a rectangular crosssection between its ends and center as shown in Fig. 21, and a circularcross section at its ends as shown in Fig. 22, which circular ends areadapted to rest on and fit the jOllI'. nal bearings 14 of'the caps 12.

Near the center portion of equalizing bars 15 are fixed small angleplates 16 and these are, held by-means of suitable cap screws 17, whichare adapted to rub against adjacent saddles 18, that rest on thecircular .curved portions of the equalizing bars 15 and carry the anglemetal bars 19, which taken together compose the spring plank 20. Thesaddles 18 are provided: with suitable" lugs 21 adapted to entercorresponding recesses in the bars 19 and the bars 19 are" fixed to thesaddles 18 by means of suitable bolts'22.

The spring plank 20 carries plates 23 on which rest bands 24 of theelliptic springs 25., which are bolted and secured to said plates 23 bymeans of T-bolts 26 and the plates 23 are fixed to the spring plank 20,by means of suitable bolts 27. The bolster is carried from the springs25 and between -transoms in the conventional manner and transmit theload to the spring plank 20,

from thence it is distributed between equalizing bars 15, through thesaddle 18 and from thence is carried to the caps 12, springs 11, seat 10and links 9 to the top chord 7 of the truck frame.

Any tendency of the bolster to swing transversely of the truck isprovided for by the saddles 18, which bars 15 and the caps 12 whichcarry said equalizing bars and permit an angular movement of saidequalizing bars, but as this swinging of the equalizing bars elevatesthe car body, the tendency to swing is greatly reduced, and the swingingwhen once started does not last. The links 9 do not swing at all, asthey are substantiall rigid with the top chord-7.

While I have shown and described one .em- I bodiment pf my invention, itis obvious that it is not restricted thereto, but is broad enough tocover all structures that come within the scope of the annexed claims.
